What is the purpose of this trial?

This trial focuses on testing the safety and tolerability of a new treatment called SPY002-091, an experimental treatment not previously used in humans. Researchers will administer either a single dose of the treatment or a placebo (a substance with no active ingredients) to healthy participants to observe the body's reaction. Healthy adults willing to attend all study visits and comply with testing may be suitable candidates for this trial. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, since the study is for healthy volunteers, it's likely that participants should not be on any regular medications. Please check with the study coordinators for more details.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that SPY002-091 was tested on healthy individuals, and single doses up to 1500 mg were generally well tolerated. Most participants did not experience serious side effects, and no serious health problems were reported, indicating a positive safety profile. Common mild side effects included headaches, drowsiness, and weakness, but these also occurred with a placebo. This suggests that SPY002-091 is likely safe for most people, at least in the short term, based on current evidence. ^{1 2 3 4 5}

Why are researchers excited about this study treatment?

Researchers are excited about SPY002-091 because it offers a novel approach compared to existing treatments. Unlike current options that typically rely on established mechanisms, SPY002-091 is being tested for its unique mechanism of action that could potentially offer improved safety and efficacy. This treatment is designed to work differently, which could mean fewer side effects and better outcomes for patients. Such innovation is what makes SPY002-091 a promising candidate in the field.

What evidence suggests that SPY002-091 could be effective?

In this trial, participants will receive either SPY002-091 or a placebo. Research shows that SPY002-091 targets specific processes in the body that cause inflammation. Lab studies have shown its potential to reduce signs of inflammation. While data on its effectiveness in humans is not yet available, its mechanism suggests it could help with inflammation-related conditions. The trial aims to determine if it can stop the processes that lead to inflammation. Early results from lab models are promising, but human trials are necessary to confirm these effects.

What Are the Treatments Tested in This Trial?

Interventions

• Placebo
• SPY002-091

Trial Overview The study is testing SPY002-091 in its first human trial. It's a Phase 1 trial where participants are randomly given either SPY002-091 or a placebo without knowing which one they receive to evaluate safety, tolerability, and how the body processes it.

How Is the Trial Designed?

Group I: SAD Cohorts, Experimental Arm Experimental Treatment 1 Intervention

Participants will receive a single dose of SPY002-091 in a dose escalation format

Group II: SAD Cohorts, Placebo Arm Placebo Group 1 Intervention

Participants will receive a single dose of placebo

Published Research Related to This Trial

The study systematically analyzed placebo effects from randomized, placebo-controlled trials, revealing that while placebos can influence clinical symptoms, they do not affect laboratory values like blood glucose in diabetics.

Placebo side effects were found to be similar to those of active treatments, highlighting the importance of careful placebo use in clinical research to ensure patient safety and informed consent.

Placebo treatment is effective differently in different diseases--but is it also harmless? A brief synopsis. Weihrauch, TR.[2019]

In a review of 24 First-in-Man studies involving 1,017 healthy male volunteers, the incidence of adverse events (AEs) was low, with 98.3% of AEs being mild or moderate, indicating a favorable safety profile for small molecules in Phase I trials.

Only 0.4% of treatments resulted in serious adverse events, all of which were not medically concerning and did not require hospitalization, suggesting that small molecule trials can be conducted safely in healthy volunteers.

The workshop highlighted the potential of using very low dose human studies (microdoses) to assess drug candidates earlier in the development process, which could improve the selection of effective drugs while ensuring volunteer safety.

Incorporating advanced techniques like accelerator mass spectrometry (AMS) and positron emission tomography (PET) in these early human studies could provide valuable data on how drugs are processed in the body, potentially reducing reliance on animal testing.

In a comprehensive review of 54 phase-I studies involving 1015 healthy volunteers over 10 years, the overall incidence of adverse events was found to be 12.8%, with a higher rate for active drugs (13.7%) compared to placebo (7.9%).

Most adverse events were minor, with only 3% classified as severe, and no deaths or life-threatening events reported, highlighting that while adverse events are common in phase-I trials, they are typically not serious.

A new checklist called TIDieR-Placebo has been developed to improve the reporting of placebo or sham interventions in clinical trials, ensuring that researchers clearly describe these components alongside active treatments.

The checklist was created through expert consultation and aims to enhance the transparency of trial results, which is crucial for accurately assessing the benefits and harms of active interventions.

In a review of 109 clinical studies with 1228 healthy volunteers, 19% reported adverse events during placebo administration, highlighting that even without active treatment, participants can experience side effects.

Adverse events were more common with repeated dosing (28%) and among elderly participants (26%), with headaches, drowsiness, and asthenia being the most frequently reported issues, indicating that placebo effects can significantly influence safety evaluations.

A ten-day trial demonstrated a significant reduction in viral load among volunteers, indicating potential efficacy of the treatment being tested.

The results suggest that the intervention may effectively lower the amount of virus present in the body, which is crucial for managing viral infections.

In a five-year analysis of 1,559 healthy volunteers across 142 phase I studies, the overall incidence of adverse events (AEs) was 8.8%, with most AEs being mild or moderate in severity, indicating that while AEs are common, they are generally not severe.

The incidence of AEs was significantly higher in multiple-dose studies compared to single-dose trials, highlighting the importance of study design in assessing the safety profile of active drugs, with a notable increase in AEs on the first day of drug administration.

Adverse events in volunteers participating in phase I clinical trials: a single-center five-year survey in 1,559 subjects. Lutfullin, A., Kuhlmann, J., Wensing, G.[2019]

Adverse events (AEs) are reported in 49.1% of trial participants in placebo groups, indicating that these events are quite common and not solely due to the natural progression of conditions.

The prevalence of AEs in placebo groups (6.51%) is higher than in untreated groups (4.25%), suggesting that the nocebo effect may play a significant role in the experience of AEs during clinical trials.
